Here are found the lynx, the " mountain lion " or puma, the prairie and timber wolves, the jack rabbit, the prairie dog (gopher), the black, the brown and, occasionally, the grizzly bear.
The grizzly bear is said to lose this power of climbing in the adult stage.
The grizzly bear is now rare in the United States, save in the Yellowstone Park and the Clearwater Mountains of Idaho, though more common in British Columbia.
Bison no longer roam the plains, and the elk has been driven out; but among the larger mammals still to be found in certain districts are the deer, prong-horn (in small numbers), puma, coyote, timber wolf, lynx (Lynx rufus and Lynx Canadensis) and the black and grizzly bear.
The film explores the life and death of amateur grizzly bear expert and wildlife preservationist Timothy Treadwell.
